Abstract

The quickest path problem deals with the transmission of a message of size σ from a source to a destination with the minimum end-to-end delay over a network with bandwidth and delay constraints on the links. The path-table that maps all intervals for σ to the corresponding quickest paths can be computed in O(m 2+mn log n) time, where n and m are the number of nodes and links of the network, respectively. We propose linear-time algorithms that update the path-table after a increase or decrease bandwidth of a link or a path, respectively.
